  1. 1. Spänning och motstånd : en studie av samtal i karaktärsämnet på ett elprogram

    Författare :Fredrik Lundström; Anna Lindström; Fritiof Sahlström; Mathias Broth; Nigel Musk; Örebro universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; challenging activities; conversation analysis; vocational training; apprenticeship; poetics; classroom interaction; electrician; multimodal; Svenska språket; Swedish Language;

    Sammanfattning : This study examines how teaching is interactionally accomplished within a vocational program for students studying to become electricians. The data is drawn from video recordings of classroom lectures as well as hands-on instructions at construction work sites. LÄS MER

  3. 2. Spänning i offentlig upphandling - Om användande av ett strategiverktyg

    Författare :Tore Johansson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; public procurement; Offentlig upphandling; tension; Spänning; strategy tool; strategiverktyg; strategy construction; hierarchal levels of practice; strategic factor categories; strategy-as-practice; strategi som praktik; tension;

    Sammanfattning : Tension in Public Procurement - The usage of a strategy tool: Public procurement is about public purchases, but also about sale of goods and services to the public sector. In research, public procurement is usually analyzed from a market or a transactional perspective. LÄS MER

  4. 3. Laughter, excitement, and suspense in preschool : Choreographing emotional stances as a multiparty achievement

    Författare :Emilia Holmbom Strid; Asta Čekaitė; Sally Wiggins Young; Carolin Demuth; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social interaction; Emotional displays; Adult-child interaction; Child-child interaction; Joint attention; Multiparty interaction; Peer cultures; Samspel; Känslouppvisningar; Vuxen-barn samspel; Barn-barn samspel; Delad uppmärksamhet; Flerpartssamspel; Kamratkulturer;

    Sammanfattning : Most research on emotions, including that which takes a social perspective, is directed at negative emotions and their manifestation in social situations that involve conflicts, disputes, and arguments. This thesis instead aims to address children’s heightened positive emotions and their interactional functions within the peer group and in learning encounters with teachers in preschool. LÄS MER

  5. 4. Skolplanschen : Argument i spänning mellan bild och text, perspektiv och kontext

    Författare :Olof Gustaf Jonsson; Ulf P. Lundgren; Elisabet Malmström; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; visual argumentation; structural; normative texts; curricula; Education; Pedagogik; Pedagogik; Education;

    Sammanfattning : This study reaches back to a reading tradition that can be traced to Antiquity and Medieval times; a reading tradition where images and text joined in a symbiosis conveyed the story to the reader. From initially being closely interconnected, the connections between image and text have separated, and the strength of the coupling between image and text has varied over time. LÄS MER

  7. 5. On the Internal Dynamics and AC-Motor Drive Application of Modular Multilevel Converters

    Författare :Antonios Antonopoulos; Hans-Peter Nee; Lennart Harnefors; Hirofumi Akagi; KTH; []

    Sammanfattning : This thesis is an effort to investigate the operation and the performanceof modular multilevel converters (M2Cs). Proven to be the most promisingtopology in high-voltage high-power applications, it is necessary to put aneffort in understanding the physical laws that govern the internal dynamicsof such converters, in order to design appropriate control methods.
